Liquid coconut oil, often referred to as fractionated coconut oil, is made through a process called fractionation. This process separates the different types of fats within coconut oil, resulting in a product that stays liquid at room temperature.
Understanding Fractionation
The key to making liquid coconut oil lies in understanding its fat composition. Coconut oil contains various fatty acids, each with a different melting point. Fractionation exploits these differences.
The Fractionation Process
Here's a breakdown of how fractionated coconut oil is made:
-
Heating: The process begins by heating the coconut oil above its melting point. This ensures that all the fatty acids are in a liquid state.
-
Controlled Cooling: The heated oil is then slowly cooled. As the temperature decreases, the higher melting point fatty acids, primarily long-chain triglycerides (LCTs), begin to solidify.
-
Separation: The solid fraction (the LCTs) is then physically separated from the remaining liquid. This separation can be achieved through various methods, such as filtration or centrifugation. These methods mechanically remove the solid fats.
-
Result: The remaining liquid is primarily composed of medium-chain triglycerides (MCTs), which have lower melting points and remain liquid at room temperature. This is the fractionated coconut oil, or liquid coconut oil.
Why Fractionate Coconut Oil?
Fractionation provides several benefits:
- Extended Shelf Life: Removing the LCTs improves the oil's stability and extends its shelf life.
- Liquid at Room Temperature: This makes it more convenient for various applications.
- Improved Texture: Fractionated coconut oil is often used in cosmetics and personal care products for its smooth, non-greasy texture.
- Concentrated MCT Content: This is desirable for those seeking the potential health benefits of MCTs.
Summary
In summary, liquid coconut oil is produced through the fractionation of regular coconut oil. This process involves heating, cooling, and separating the different types of fatty acids to isolate the liquid MCTs. This results in a stable, liquid oil with a long shelf life and desirable properties for various applications.
